Variable-frequency constant-pressure water supply device
The invention discloses a variable-frequency constant-pressure water supply device which comprises a control unit (1), a driving unit (2), a direct-current motor (3) and a water pump (4). Water can be supplied to a building (6) by the water pump (4) via a water supply pipeline, a pressure sensor (5) and an electric valve (7) are arranged on the water supply pipeline, the pressure sensor (5) is connected with the control unit (1), an output end of the control unit (1) is connected with the driving unit (2), the driving unit (2) is connected with the direct-current motor (3), and the direct-current motor (3) is connected with the water pump (4) by a transmission shaft. The variable-frequency constant-pressure water supply device has the advantage that the water can be stably supplied at constant pressures.
